Typescript module not found 编译时出错

Question

当我编译 typescript 时，出现如下错误。 我使用webpack-dev-server运行它。

Module not found: Error: Can't resolve 'i18n' in ...
Module not found: Error: Can't resolve '../moment' in ...

但是在我这样导入它们的代码中

import * as i18n from "i18n";
import * as moment from 'moment';

并且没有下划线表示 static 检查器确定它已找到。

tsconfig.js

{
    "compilerOptions": {
        "outDir": "./dist",
        "noImplicitAny": true,
        "moduleResolution": "Node",
        "resolveJsonModule": true,
        "module": "ES2020",
        "target": "ES2020",
        "lib": [
            "ES2020"
        ],
        "allowJs": false,
        "alwaysStrict": true
    },
    "include": [
        "./src"
    ]
}

webpack.config.js

const path = require('path');

module.exports = {
    entry: './src/bot.ts',
    module: {
        rules: [
            {
                test: /\.ts$/,
                use: 'ts-loader',
                exclude: /node_modules/,
            },
        ],
    },
    resolve: {
        extensions: ['.ts'],
    },
    output: {
        filename: 'bot.js',
        path: path.resolve(__dirname, 'dist')
    }
};

package.json

{
    "name": "app",
    "version": "1.0.0",
    "description": "",
    "scripts": {
        "start": "npm dist/bot",
        "dev": "webpack-dev-server",
        "build": "webpack --mode production",
        "lint": "npx eslint . --ext .ts"
    },

        "i18n": "^0.10.0",
        "moment": "^2.27.0"
    }
}

我怎样才能解决这个问题？

Answer 1

您可能需要在 VS Code 上重新启动 typescript。

一种方法是

1. go 在菜单中“开始”，
2. select '转到文件'
3. 键入大于号 (>)
4. 然后输入“TypeScript：重启 TS 服务器”
5. 按回车

您也许可以使用快捷键来更快地访问菜单项 Control-shift-P，以跳到第 4 步。
